Kedu ihe dị iche n'etiti HPMC na Mhec?

Hydroxypyl Methylcelllose (HPMC Hydroxyythythythythythythythythythythythythythythythythythythythythythythythythyythythythythyythyythythyythyyth na-eji ụlọ ọrụ dị iche iche dị ka iwu, ọgwụ, na ihe ịchọ mma. N'agbanyeghị na-ekerịta ụdị ihe owuwu na ngwa ha, enwere ọdịiche dị n'etiti ha abụọ.

1. Ihe mejupụtara kemịkalụ:

HPMC (hydroxylthylthylthylcelllose): hpmc bụ polymer polymer sitere na cellose. A na-emepụta ya site na mgbanwe kemịkal nke cellulose, nke na-esite na osisi pulp ma ọ bụ akwa akwa. Mgbanwe ahụ gụnyere ịgwọ ọrịa cellulose na alkali, nke etherification na propylene oxide na methyl chloride iji webata ndị dị iche iche na methyl na Belllose Backbone.

Mhec (Metylyythyythythythyth Cellulose): Mhec bụkwa nke cellulose euthatara site na ngbanwe kemịkal nke cellose. Yiri HPMC, ọ na-agagharị mmeghachi omume nke mmeghachi omume methyl na otu hydroxyethyl na Cellulose Backbone. A na-eji usoro nke akwara na-emeso ihe na alkali na Methery chloride na ethlene oxide.

2.. Chemical Commes:

Ọ bụ ezie na ha abụọ HPMC na MHEC na-ekerịta Cellulose Backbone, ha dị iche na ụdị na nhazi na nhazi nke otu dị iche iche jikọtara ọnụ na azụ azụ.

Ihe owuwu HPMC:
A na-ekesasị Hydroxyl.
Oke nke hydroxypropyyyl na methyl dị iche iche dabere na usoro nrụpụta na Njirimara ịchọrọ.

Ihe Mhec Mhec:
Methyl na Hydroxyesy Dị iche (-ch2chohch3) na-arapara na Balulose Backbone.
A ga-edozirịrị ogo nke methyl na Hydroxyethyyyyyyyyyl n'oge njikọta iji nweta nkọwapụta.

3. Njirimara:

Njirimara HPMC:
HPMC ihe ngosi dị elu sosduty, na-akpụzi ntụgharị na azịza victotion.
Ọ nwere ezigbo ihe nnweta nzụlite nzụlite dị mma, na-eme ya dị mma maka ngwa chọrọ mkpuchi mkpuchi.
HPMC na-enye ezigbo adhesion ma na-ejide onwe ya, ịkwalite cohesion n'ọtụtụ usoro.
Enwere ike ịhazi viscosis nke HPMC nwere ike ịhazi site na idozi ogo nke dochie anya ya.

Ihe Njirimara Mhec:
MHEC na-egosikwa sọsọ mmiri, mana solution ya nwere ike ịdị iche dabere na ogo nke dochie anya na ọnọdụ okpomọkụ.
Ọ na-etolite ihe ngwọta doro anya na omume pseudoploplastic, na-egosipụta akụrụngwa Shear-thinning.
Mhec na-enye ọmarịcha mmetụta ma sie ike na sistemụ.
Dị ka HPMC, enwere ike ịchịkwa viscosis nke MHEC site na-agbanwe ogo nke nbanye na oke molecular.

4. Ngwa:

Ngwa HPMC:
Industrylọ ọrụ owuwu: A na-eji HPMC mee ihe n'ọtụtụ mgbawa, na-agbaze agbada, na ndagwurugwu nke tames, na tile adhesives iji meziwanye ọrụ ọrụ, njigide mmiri, na adresion.
A na-arụ ọrụ ọgwụ: a na-eji HPMC a na-ejikọ ọnụ, usoro a na-achịkwa, ngwọta nke ophthalmic, na nkwadebe na akụrụngwa ya.
Nri na ịchọ mma: HPMC na-eje ozi dị ka onye na-ahụ maka ihe ndị na-eme mkpọtụ, kwụsie ike, kwụsie ike, na emunsufier na nri nri, ihe nlekọta onwe onye, ​​na ihe ịchọ mma.

Ngwa Mhec:
A na-arụ ọrụ ụlọ ọrụ owuwu: A na-ewekarị Mhec na usoro iwu ciment dị ka tile adhesives, rendes, na ndị na-egwu mmiri, ọrụ ike na adresion.
A na-eji eserese na mkpuchi: A na-eji Mhec dị ka Rheelogy Thinaiology na eserese mmiri, mkpuchi, na inks ijikwa viscosity, na-egbochi ịkwali ihe.
Usoro ọgwụgwọ: MHEC na-ahụ ngwa na nkwụpụta ọgwụ, nkwadebe ọgwụ oghethalmic, ma na-achịkwa usoro onunu ogwu ma kwụsie ike ma kwụsie ike.

5. Uru:

Uru nke HPMC:
HPMC na-enye ihe ndị dị elu na-akpụ akpụ ihe dị elu, na-eme ka ọ dị mma maka nchekwa mbadamba ma na-achịkwa ya.
Ọ na-egosipụta ezigbo ndọnye na njiri maramara, na - eme ka njikọta nke usoro dị iche iche.
HPMC na-enye nkọwa dị iche iche n'ịgbazi viscosity na mgbakwunye Njirimara Ngwọta.

Uru nke Mhec:
Mhec na-egosipụta mmetụta dị iche iche ma kwụsie ike na sistemụ ahụ, na-eme ka ọ dị mma maka agba, owuwu, na usoro nhazi ọgwụ.
Ọ na-enye ezigbo njigide mmiri dị mma, na-eme ka ọrụ na ndọghachi azụ na ngwaahịa ciment.
MHEC na-enye pseudoploplastic omume, ikwe ka ọ dị mfe ngwa ma mee ka njirimara dị elu na mkpuchi na eserese.

Ọ bụ ezie na ma HPMC na Mhec bụ ndị a na-ekwu maka ngwa mkpụrụ osisi nwere ngwa ahụ, ha na-egosipụta ọdịiche na kemịkalụ kemịkal ha, ihe owuwu, na uru ha. A maara HPMC maka ihe nkiri a na-akpụ akpụ na ngwa agha ya, ebe mhec kasịnụ na ndagide, na-emesi ike, yana mmetụta njigide. Ghọta ihe ndị a dị oke mkpa maka ịhọrọ nke kachasị mma nke mkpụrụ ndụ maka ngwa ndị akọwapụtara na ụlọ ọrụ dị iche iche.
